This is due to the `duplicate_post()` function in `includes/api.php` using `$wpdb->insert()` directly to the `wp_postmeta` table instead of WordPress's standard `add_post_meta()` function, which would call `is_protected_meta()` to prevent lower-privileged users from setting protected meta keys (those starting with `_`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary protected post meta keys such as `_wp_page_template`, `_wp_attached_file`, and other sensitive meta keys on duplicated posts via the `customMetaData` JSON array parameter in the `/wp-json/post-duplicator/v1/duplicate-post` REST API endpoint." } ], "title": "Post Duplicator <= 3.0.8 - Missing Authorization to Authenticated (Contributor+) Protected Post Meta Insertion via 'customMetaData' Parameter", "references": [ { "url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/e5c86f72-934c-4f3b-ab2a-65df1490ca8a?source=cve" }, { "url": "https://plugins.trac.wordpress.org/browser/post-duplicator/tags/3.0.6/includes/api.php#L923" }, { "url": "https://plugins.trac.wordpress.org/browser/post-duplicator/tags/3.0.6/includes/api.php#L843" }, { "url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3463768%40post-duplicator%2Ftrunk&old=3459096%40post-duplicator%2Ftrunk&sfp_email=&sfph_mail=" } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "CWE-862 Missing Authorization", "cweId": "CWE-862", "type": "CWE" } ] } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N", "baseScore": 4.3, "baseSeverity": "MEDIUM" } } ], "credits": [ { "lang": "en", "type": "finder", "value": "Hung Nguyen" } ], "timeline": [ { "time": "2026-02-11T16:25:17.000Z", "lang": "en", "value": "Vendor Notified" }, { "time": "2026-02-24T21:12:32.000Z", "lang": "en", "value": "Disclosed" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-02-25T21:00:26.768409Z", "id": "CVE-2026-2301", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-02-25T21:00:43.772Z" } } ] } }
